There is a bit of difference in magnitude, though, between the two cases you cite. Bush attempts to label those who disagree with him as traitors, but nobody has been convicted of that and there are plenty of officers in the military who think and say that what he's doing is at least misguided, if not worse.

Meanwhile, the Islamists not only "label" these cartoonists as blasphemers, but follow it up with rifle attacks and physical injury.
